The Department of Environmental Health Science (EHS) is housed in the Environmental Health Science Building on UGA’s South Campus (Building 1050 on the UGA Interactive Campus Map). Our physical address, maps, and driving instructions can be found here.
The Environmental Health Science Building is approximately 7500 square-feet in size of which over half is laboratory space and the remainder is split between classroom and office space. In addition, EHS faculty members have their laboratories in the Paul D. Coverdell Center for Biomedical and Health Sciences and Rhodes Animal Sciences Center.
The Department of Environmental Health Science houses office space for ten faculty members, two administrative staff, research staff, adjunct faculty, post-doctoral researchers, visiting scholars, and graduate students.

Biomarker, Cancer Etiology and Prevention, and Mycotoxins Research Laboratories
Rooms 304 and 306 in the EHS Building, Room 225B, and Room 226 in the Coverdell Building contain a biomarker research laboratory, a genomics and proteomics laboratory, a cell culture room (225B), and biospecimen repository space for conducting biomarkers research, cancer etiology and prevention studies, mechanic toxicological studies, and mycotoxins research. Animals, normal and cancer human cells, and human biospecimen (blood, urine, and tissues) were used in these laboratories for development and validation of carcinogen-specific biomarkers, molecular epidemiological studies, chemoprevention studies, and mechanic-driven molecular toxicological studies of mycotoxins. These laboratories are well-established with many pieces of equipment for analytical and biochemical analyses, including a Thermo LC/MSn system, ESA HPLC-CoulArray system, two Agilent HPLC systems (1100 and 1200) with autosampler, Diodearray UV detector, and Fluorescence detector, one Thermo HPLC system including autosampler, Diodearray UV detector, and Fluorescence detector; a Beckman Coulter UV/VIS spectrophotometers ( DU800), a 96 well microplate reader for ELISA, a Labco speed vacuum system, a chromatography cool cabinet, a flourometer, multiple centrifuges, and microanalytical balance. Laboratories in Coverdell Building also equipped with a Fast Real Time 7500 PCR system, two regular PCR machines, an image system, 1- and 2-D gel facilities for genotypic and proteomic analysis. The cell culture facility including a culture hood, two CO2 incubators, and an Olympus inverted microscope can conduct researches on human liver, esophageal, lung, breast, and prostate cells studies. The biospecimen repository equipped with six Reveco -80’C freezers two -20 °C freezers and crytogenic facility has provided good resources for storage of human cells and biospecimen.

Environmental Exposure Assessment and Air Quality Laboratories
The Air Quality Laboratory is used to stage field studies, process air quality samples, and maintain and store air sampling equipment. Rooms 126 and 103 in the EHS building are dedicated primarily for research in air quality and environmental exposure assessment. The air quality lab (room 126) is outfitted with a standard wet lab facility and a freezer to store environmental samples. It also has a small climate-controlled room attached to it that is outfitted with an analytical balance (Cahn 35 electro-microbalance) used to weigh filters for air monitoring research. The main portion of the laboratory is 350 ft2 and accommodates experiments in both traditional exposure assessment using environmental and biological samples, and environmental epidemiology. The lab has four computer workstations for data reduction and analysis for environmental exposure assessments and storage space for field instrumentation. Additional field instruments for air quality research (cyclone pumps, high capacity filter units, etc.) are stored in the EHS storage room (105E; 306 ft2). The lab includes a dedicated and climate-controlled room for high-precision gravimetric analysis of fine particle samples. Specialized equipment for conducting research in air quality include a variety of particle and gas sampling systems such as the Federal Reference Method samplers for PM2.5, inertial impactors, and cyclones, as well as a host of absorption samplers for gases and aerosols.
